Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 146.19 g/mol gives (R)-3,6-Diaminohexanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(R)-3,6-Diaminohexanoic acid (CAS 51703-81-2), molecular formula C6H14N2O2 and molecular weight 146.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (R)-3,6-Diaminohexanoic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.19 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.
