Chemical Structure

甲瓦龙酸内酯-甲基-<SUP>13</SUP>C<SUB>1</SUB> CAS 75644-54-1 chemical structure

Description

甲瓦龙酸内酯-甲基-<SUP>13</SUP>C<SUB>1</SUB> (CAS 75644-54-1), molecular formula C5[13C]H10O3 and molecular weight 131.13 g/mol, is a CATO reference standard with documented purity and traceability.

甲瓦龙酸内酯-甲基-<SUP>13</SUP>C<SUB>1</SUB> (C5[13C]H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
