Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 3,4-diaminobenzoate 3,4-diaminobenzoic acid methyl ester 3,4-diamino-benzoic acid methyl ester benzoic acid, 3,4-diamino-, methyl ester methyl 3,4-diaminobenzenecarboxylate methyl-3,4-diaminobenzoate 36692-49-6.
Methyl 3,4-diaminobenzoate 3,4-diaminobenzoic acid methyl ester 3,4-diamino-benzoic acid methyl ester benzoic acid, 3,4-diamino-, methyl ester methyl 3,4-diaminobenzenecarboxylate methyl-3,4-diaminobenzoate 36692-49-6 (CAS 36692-49-6), molecular formula C8H16N2O2 and molecular weight 172.22 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Methyl 3,4-diaminobenzoate 3,4-diaminobenzoic acid methyl ester 3,4-diamino-benzoic acid methyl ester benzoic acid, 3,4-diamino-, methyl ester methyl 3,4-diaminobenzenecarboxylate methyl-3,4-diaminobenzoate 36692-49-6 (C8H16N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 172.22 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
