If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

Application
- Sensitive and selective spectrophotometric assay of piroxicam in pure form, capsule and human blood serum samples via ion-pair complex formation.: This study presents a sensitive spectrophotometric method for determining piroxicam in various forms by forming an ion-pair complex with bromocresol green. This method enhances the accuracy and selectivity of piroxicam assays, providing valuable applications in pharmaceutical analysis and clinical diagnostics (Alizadeh & Keyhanian, 2014).
- A high-throughput colorimetric assay to measure the activity of glutamate decarboxylase.: Bromocresol green is utilized in a high-throughput colorimetric assay to measure the activity of glutamate decarboxylase. This assay is crucial for biochemical studies involving enzyme kinetics and could be applied in drug discovery and metabolic engineering research (Yu et al., 2011).
- Spectrophotometric and HPLC determinations of anti-diabetic drugs, rosiglitazone maleate and metformin hydrochloride, in pure form and in pharmaceutical preparations.: The use of bromocresol green in spectrophotometric and HPLC methods enhances the detection and quantification of anti-diabetic drugs. This research is vital for ensuring the quality and efficacy of pharmaceutical products (Onal, 2009).
- Spectrophotometric determination of lamotrigine in pharmaceutical preparations and urine by charge-transfer complexation.: Bromocresol green is employed in the spectrophotometric determination of lamotrigine, facilitating the analysis of this antiepileptic drug in pharmaceutical and biological samples. This application is essential for therapeutic drug monitoring and pharmaceutical quality control (Alizadeh et al., 2008).

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
