83907-40-8 Usage
Uses
Used in Biological Research:
6-methoxy-N-(3-sulfopropyl)quinolinium is used as a fluorescent chloride indicator for assessing voltage-sensitive chloride transport in placental microvillus vesicles. It helps in understanding the mechanisms of chloride transport across biological membranes.
Used in Cellular Analysis:
In isolated human erythrocytes, SPQ is used as a tool to continuously quantify intracellular calcium efflux induced by parathyroid hormone, forskolin, and phorbol 12-myristate 13-acetate (PMA). This application aids in studying the effects of these agents on cellular calcium regulation.
Used in Ion Channel Research:
6-methoxy-N-(3-sulfopropyl)quinolinium is utilized to determine the type of ion conductance induced by the cystic fibrosis transmembrane conductance regulator (CFTR) in HEK293 cells expressing pTrial10-CRTR2. This application is valuable for investigating the function and regulation of ion channels, particularly in the context of cystic fibrosis.
Check Digit Verification of cas no
The CAS Registry Mumber 83907-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,0 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83907-40:
(7*8)+(6*3)+(5*9)+(4*0)+(3*7)+(2*4)+(1*0)=148
148 % 10 = 8
So 83907-40-8 is a valid CAS Registry Number.

Dramatic rate acceleration was observed for N-sulfopropylation of heterocyclic compounds (1a-h) using 1,3-propane sultone(2) under microwave irradiation affording the N-sulfopropylated compounds (3a-h) in 68-95% yield.
Syntheses of Fluorescent Dyes. XIV. Standards for Fluorescent Measurements in the Near Neutral pH-Range
Wolfbeis, Otto S.,Urbano, Edmund
, p. 841 - 843 (2007/10/02)
Highly fluorescent cationic indicators have been obtained by reaction of heterocyclic nitrogen bases with 1,3-propane sultone.Unlike the bases themselves, the fluorescence intensity of the cationic salts is practically pH-independent in the neutral pH-range, which makes them useful reference substances in measuring fluorescence intensities in physiological studies.Furthermore, they are sufficiently water soluble, the fluorescence maxima covering the wavelength range from 440 to 530 nm. 2-(3-Sulfonatopropyl)harmanium, (5) appears to be the most useful compound for intra- and extracellular liquids, since its fluorescence is not quenched by chloride ion.
