5208-49-1 70YIT2H368 4-Carene, cis-(-)- UNII-70YIT2H368 Bicyclo(4.1.0)hept-2-ene, 4,7,7-trimethyl-, (1R,4R,6S)- 4-Carene, (1S,3R,6R)-(-)- (CAS 5208-49-1) is a high-purity analytical reference standard with the molecular formula C10H16 and a molecular weight of 136.23 g/mol.
Owing to an organic framework, 5208-49-1 70YIT2H368 4-Carene, cis-(-)- UNII-70YIT2H368 Bicyclo(4.1.0)hept-2-ene, 4,7,7-trimethyl-, (1R,4R,6S)- 4-Carene, (1S,3R,6R)-(-)- is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
