(2r)-3-Carbamoyl-2-hydroxypropanoic acid CAS 82310-91-6

Description

The occurrence of (2r)-3-Carbamoyl-2-hydroxypropanoic 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.

(2r)-3-Carbamoyl-2-hydroxypropanoic acid (CAS 82310-91-6) is a high-purity analytical reference standard with the molecular formula C4H7NO4 and a molecular weight of 133.10 g/mol.

Structurally, (2r)-3-Carbamoyl-2-hydroxypropanoic acid (C4H7NO4) contains a carbohydrate-derived structure, an amide group. 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 133.10 g/mol, it falls into the low-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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
