Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including L-Lysine compound with carbonic acid (1:1).
L-Lysine compound with carbonic acid (1:1) (CAS 28231-58-5) is a high-purity analytical reference standard with the molecular formula C6H14N2O2CH2O3 and a molecular weight of 208.21 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, L-Lysine compound with carbonic acid (1:1) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.21 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.
