Chemical Structure
Description
The occurrence of (S)-2-Amino-4-boronobutanoic acid is closely related to a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-2-Amino-4-boronobutanoic acid (CAS 334700-46-8), molecular formula C4H10BNO4 and molecular weight 146.94 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, an amide group, (S)-2-Amino-4-boronobutanoic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.94 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
