Each shipment is accompanied by a Certificate of Analysis. Products sold by ISOFLEX are guaranteed to meet the specifications described in the Certificate of Analysis, providing there is no evidence of foreign contamination introduced after shipment from our facility. Compound weight is calculated using standard stoichiometry methods, without correction for enrichment. Quoted isotopic enrichments are guaranteed within 0.5%, unless otherwise noted.
