N,N-Dimethylglycine hydrochloride is a glycine-derived amino acid derivative in which the amino nitrogen is substituted with two methyl groups, yielding an N,N-dimethylated amino acid salt. The molecule contains a carboxyl functional group and a dimethylamino group, with the hydrochloride counterion associated to form the hydrochloride salt that modulates basicity and improves handling relative to the free base. It is used in peptide and amide synthesis as a chemically defined building block for introducing an N,N-dimethylglycine motif, as well as in labeling and analytical workflows where a stable, structurally characterized amino acid derivative is needed.
CAT No: CP00901
N,N-Dimethylglycine hydrochloride is a chiral amino acid derivative in which the glycine backbone is substituted on nitrogen with two methyl groups, forming a zwitterionic amino acid motif as the hydrochloride salt. The molecule contains a protonated amine (as chloride counterion) and a carboxylic acid functional group, enabling salt formation, acid-base tuning, and controlled reactivity in aqueous and mixed-solvent systems. The N,N-dimethyl substitution alters nucleophilicity and peptide-coupling behavior relative to glycine, while the hydrochloride form facilitates handling as a stable, water-compatible intermediate. As a small, stereochemically relevant chiral building block precursor, it can be converted into activated derivatives that participate in amide formation, N-alkylation sequences, and downstream synthesis of amino acid analogs used in biochemical and industrial workflows.
1. Chemical Synthesis Intermediate
N,N-Dimethylglycine hydrochloride functions as an amino acid-based intermediate for synthetic organic chemistry where a dimethylated glycine unit is required for amide bond construction or further functionalization. The carboxylic acid group can be transformed into acylating intermediates, while the tertiary amine character of the N,N-dimethyl group supports predictable salt behavior and controlled partitioning between aqueous and organic phases. The hydrochloride counterion can be leveraged to manage protonation state during coupling or derivatization steps, supporting reproducible downstream transformations into protected or activated forms. The resulting derivatives can serve as building blocks for fine chemical synthesis and for preparing chiral or non-chiral amino acid analogs used in multi-step route design.
2. Peptide Coupling Building Block
N,N-Dimethylglycine hydrochloride is suitable for peptide synthesis workflows that incorporate dimethylglycine as a structural element to modulate backbone polarity and steric environment. The molecule's amino acid functionality provides a defined handle for converting the carboxyl group into coupling-ready activated species, while the N,N-dimethyl substitution influences amide-forming reactivity and can affect the stability of intermediates during peptide assembly. Hydrochloride salt formation supports solubility in polar media, which can be advantageous when preparing peptide building block solutions and for preparing subsequent coupling reagents. Dimethylglycine-containing peptide segments can then be used in peptide analog construction and in studies where altered backbone electronics or conformational preferences are encoded into the sequence.
3. Biochemical Research Reagent
N,N-Dimethylglycine hydrochloride can be employed in chemical biology and biochemical research as a small amino acid derivative for probing amino acid transport, methylation-related pathways, or metabolic-like labeling strategies in controlled experimental systems. The presence of both a carboxyl group and a tertiary amine enables ionic interactions with biomolecular binding sites and supports incorporation into aqueous assay formats. The N,N-dimethyl substitution provides a distinct chemical identity compared with glycine, enabling researchers to distinguish dimethylated amino acid behavior in analytical readouts and reaction monitoring. Downstream preparation of conjugatable or derivatized analogs from this hydrochloride can support biochemical investigation of amino acid recognition, metabolic intermediates, and reagent-based mechanistic studies.
4. Chiral Amino Acid Derivatization
N,N-Dimethylglycine hydrochloride serves as a chiral amino acid intermediate for stereochemically defined derivatization routes in which the dimethylglycine stereocenter is preserved through selective functional group transformations. The carboxyl group can be used to generate protected acid derivatives or activated esters/amides, while the N,N-dimethyl amine can be maintained or temporarily masked depending on the desired chemoselectivity. Hydrochloride salt handling supports consistent starting material behavior for conversion into protected amino acid synthesis intermediates used in multi-step chiral building block production. Stereodefined dimethylglycine derivatives can then be carried forward into peptide science, peptidomimetic construction, or other chiral scaffold assembly where maintaining the stereochemical configuration is necessary.
5. Pharmaceutical Intermediate Preparation
N,N-Dimethylglycine hydrochloride is applicable to pharmaceutical intermediate preparation and process chemistry where amino acid-like functionality is required as a manageable, water-compatible feedstock. The amino acid salt form supports controlled handling in manufacturing-oriented synthesis planning, and the carboxyl group enables conversion into acylating intermediates for forming amide linkages common in medicinal chemistry scaffolds. N,N-dimethyl substitution can be used to tune basicity and solubility characteristics of downstream intermediates, which can influence isolation and purification behavior in synthetic sequences. Prepared derivatives derived from this compound can be used as intermediates in the synthesis of drug-like molecules, including peptidomimetic fragments and amide-rich structures that require robust coupling chemistry.
