An article called Development and validation of a method for ionic dyes determination in guava fibrous matrix using reverse phase chromatography, published in 2021, which mentions a compound: 25956-17-6, Name is Sodium 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfonatophenyl)diazenyl)naphthalene-2-sulfonate, Molecular C18H14N2Na2O8S2, <a href=\"https:\/\/www.ambeed.com\/products\/25956-17-6.html\">Related Products of 25956-17-6<\/a>.<\/p>\n<p>In this work, a method for food dyes determination in fibrous fruit pulps was developed. The analytes Tartrazine, Twilight Yellow FCF, Erythrosine, Orange G and Allura Red were analyzed by reverse phase chromatog. with diode array (DAD) detection. The sample preparation consisted of a simple procedure, based on initial pH adjustment of the sample (pH = 10.0), followed by an extraction with acetonitrile (5.0 mL and agitation for 30 s), ultrasonic (5 min) and centrifugation (4000 rpm, 20\u00b0C, for 20 min). The supernatant had its pH adjusted to 3.0, followed by filtration. The method was validated, with the anal. curves prepared in a matrix, in the range of 50 to 150 mg kg-1 for all the analytes studied (determination coefficients (R2) > 0.99). The method veracity was evaluated in terms of recovery, obtaining recoveries of 93-110%. The repeatability was less than 13.7%, while the intermediate precision was less than 19.0%. The limits of detection and quantification were determined, being 15 and 30 mg kg-1, resp. The combined relative uncertainties were less than 13.8%. Therefore, it can be concluded that a simple method was developed, suitable for monitoring the presence of dyes in fruit pulps in routine analyzes.<\/p>\n<p>Different reactions of this compound(Sodium 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfonatophenyl)diazenyl)naphthalene-2-sulfonate)<a href=\"https:\/\/www.ambeed.com\/products\/25956-17-6.html\">Related Products of 25956-17-6<\/a> require different conditions, so the reaction conditions are very important.<\/p>\n<p>Reference:<br \/><a href=\"https:\/\/en.wikipedia.org\/wiki\/Pyrazole\">Pyrazole &#8211; Wikipedia<\/a>,<br \/><a href=\"https:\/\/www.sciencedirect.com\/topics\/chemistry\/pyrazoles\">Pyrazoles &#8211; an overview | ScienceDirect Topics<\/A><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Different reactions of this compound(Sodium 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfonatophenyl)diazenyl)naphthalene-2-sulfonate)<a href=\"https:\/\/www.ambeed.com\/products\/25956-17-6.html\">Related Products of 25956-17-6<\/a> require different conditions, so the reaction conditions are very important.<\/p>\n","protected":false},"author":8,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[727,131],"tags":[500],"class_list":["post-9707","post","type-post","status-publish","format-standard","hentry","category-25956-17-6","category-pyrazoles-derivatives","tag-m-w400-500"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.9 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Extended knowledge of 25956-17-6 | pyrazoles-derivatives<\/title>\n<meta name=\"description\" content=\"In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds.
